A Facile Fabrication of Porous and Breathable Dielectric Film for Capacitive Pressure Sensor

Flexible and wearable electronics are gaining their popularity in healthcare monitoring due to its noninvasive usage. Flexible capacitive pressure sensor can be a good candidate for monitoring physiological stimuli. Here in this study, we discuss a facile cost-effective template-based fabrication of dielectric layer for the capacitive sensor. To ensure complete breathability for wearer comfort, an improved and novel template-based technique was used to fabricate the dielectric layer. Capacitive sensors made by using such dielectric layers show good capacitive response in gentle tactile pressure range.
